+/*
+ * wxImageList is used for wxListCtrl, wxTreeCtrl. These controls refer to
+ * images for their items by an index into an image list.
+ * A wxImageList is capable of creating images with optional masks from
+ * a variety of sources - a single bitmap plus a colour to indicate the mask,
+ * two bitmaps, or an icon.
+ *
+ * Image lists can also create and draw images used for drag and drop functionality.
+ * This is not yet implemented in wxImageList. We need to discuss a generic API
+ * for doing drag and drop and see whether it ties in with the Win95 view of it.
+ * See below for candidate functions and an explanation of how they might be
+ * used.
